Pericardial Effusion in a Patient with Non-ST-Elevation Myocardial Infarction: Beware of a Hidden Malefactor

Abstract EN

Pericarditis with pericardial effusion in acute coronary syndrome is seen in patients with ST-elevation myocardial infarction specifically when infarction is anterior, extensive, and Q wave.

It is very uncommon to have pericardial effusion in a patient with non-ST-elevation myocardial infarction.

We present an elderly hypertensive patient who was diagnosed as non-ST-elevation myocardial infarction with pericardial effusion that turned out to be acute aortic dissection with catastrophic end.

We conclude that, in patients with suspected diagnosis of non-ST-elevation myocardial infarction or unstable angina, if pericardial effusion is detected on echocardiography, aortic dissection needs to be considered.
